Things You Need to Check Before Buying

Power

You can differentiate the power of an angle grinder by checking the wattage. Higher wattage is useful for heavy-duty tasks that require periods of extended use. Power capacity can vary depending on the size of the tool and the disc capacity.

7-inch models will be very powerful compared to most 4 1/2-inch models. In most cases, choose a higher wattage for the best results. For example, two angle grinders can have similar RPMs. The one with more wattage will be better for cutting hard materials like concrete or stone masonry.

Disc Size

With a 7-inch angle grinder, you need to find a matching disc. It is not a good idea to mix different disc sizes unless you know that it will not exceed the speed limit on the machine.

A compatible disc for your angle grinder provides the best results.

Speed

Angle grinders vary in speed, which is usually notated as RPMs. On average, you will see grinders with a range between 5,000 and 10,000 RPMs, or revolutions per minute.

A larger tool, like a 7-inch hand angle grinder, typically has 6,000 RPMs. You can expect more power with a larger grinder, but a lower RPM.

Consider a variable speed angle grinder if you want to work more accurately. A variable speed grinder lets you select from pre-set settings. Variable-speed models are ideal for jobs that require a delicate touch.

Power-to-Weight Ratio

A power-to-weight ratio explains the amount of power a tool has relevant to its total weight. Look for a higher power-to-weight ratio for your angle grinder. You want the tool to put off as little vibration as possible.

For example, a very powerful, light-angle grinder will not kick back at you with as much force. You can complete jobs quickly and safely.

Brushes

Brushes wear out easily with angle grinders, especially a high-powered 7-inch concrete grinder or something similar. This part is likely to wear out from lots of use for long periods.

When looking for a hand angle grinder, lookout for a model that lets you replace brushes quickly and efficiently. It is also good to know what kind of brushes it uses and whether you can find them easily on the market.

Comfort and Control

Because of the potential danger involved in mishandling an angle grinder, take comfort and control into careful consideration. These factors are not just nice to have, but essential.

The angle grinder should be a nice size and not weigh too much. Be able to hold it up easily without complaint. Beyond holding it up, you also need to be able to hold a 7-inch grinder steady.

Features to look out for in a model include anti-vibration grips and side handles. Anti-vibration designs prevent you from experiencing too much kickback from the powerful motor. Side handles are a way to control the machine with a more delicate touch.

Keeping your new angle grinder in good working order means greasing the gears from time to time. Cheaper models may not come as well-greased as they could be.

Gear Greasing

Check the gear greasing and use a recommended lubricant to keep the parts moving together smoothly.

Power Source

You can choose between corded or cordless models. Most cordless models are electric-powered and allow you to reach difficult areas. A corded 7-inch grinder is either powered with air or electricity.

A pneumatic grinder needs to be used with an air compressor. These models are light and cheap. Other corded grinders are powered with electricity and need to be plugged into a power source. You cannot move too far from a plugin, but they can run for long periods of time.

Why Do you Need a 7-Inch Angle Grinder?

Compared to a tool with a smaller disc size, a 7″ angle grinder is recommended for working with thick materials. You can cut through stone masonry and concrete using this size of angle grinder.

A 7-inch concrete grinder, however, is very powerful and you need the expertise to handle it.

Select a 7-inch angle grinder if you have a heavy-duty project to finish, like cutting through wood or concrete or other thick objects. This concrete grinder is not suitable for tasks that require a lot of precision.

How to Use a 7-Inch Angle Grinder

Step 1: Choose Disc

Based on your project, you should have an idea of what disc you require. Different types of discs are used for different tasks. For example, you would not use a grinding disc to polish metal. You need a sanding disc for polishing jobs.

Step 2: Check the Manual

Reading the manual that comes with your grinder is very important the first time you operate it. However, you should also refresh your memory every time you start a new project.

Step 3: Wear Safety Gear

A safety shield and gloves are two essential items. You can avoid a terrible injury by preparing yourself with the best safety gear.

Step 4: Secure Work

Typically, you should make sure that whatever material you are working with is secured to a work surface.

Step 5: Hold Grinder Firmly

Before starting, check that your grip is firm on the angle grinder. A 7″ angle grinder is a powerful tool and may require both hands.

Step 6: Hold Grinder Against Main Part

You should also be careful about where you place the disc against your current work. Avoid placing it at the edge. Hold it on the main part, or body.

Step 7: Turn On

After securing the grinder in your grip and placing it against the main portion, you can turn on the tool. Keep a tight grip as you work through the task, whether it be grinding, polishing, or something else.

Step 8: Switch Off

Do not abruptly turn off the tool once you are finished. Instead, lift it from the surface slowly. Switch it off after removing it completely from your work.

What are the Safety Measures to Adhere when Using an Angle Grinder?

Angle grinders of any size spin fast, but a 7-inch angle grinder spins even faster. To avoid a dangerous situation, adhere to several safety measures. First, always wear a face shield and gloves to protect your face and hands.

You should wear safety glasses. Keep the grinder turned off and unplugged until you are ready to use it. If you are changing a disc, it is best to have it unplugged, too.

When the angle grinder is turned on, make sure that any debris flies away from you and other people. Work so that the disc turns away from any sharp edges on your work. You do not want to catch the tool and cause it to malfunction.

Finally, every piece of material you are using the angle grinder on needs to be clamped down. The only thing that should be moving is the angle grinder itself.

To protect yourself from the moving parts, use the guard and keep a solid grip on the handle. A 7-inch handle angle grinder has a lot of power and may need two hands.

Also, check that the disc is working well in a protected place after attaching it. Never assume that all of your parts will work the same as the last time after storing them away. You could hurt yourself with a broken grinder.

When it comes to the best 7-inch angle grinder, The Makita GA7021 7″ Angle Grinder comes out ahead of the other options. This tool offers superb power with a 15 AMP motor and delivers up to 6,600 RPM during a project.
